Consider the following scenario. In an Active Directory domain environment, you deploy a user logon script to client computers in the domain. The logon script contains calls to Active Directory Service Interfaces (ADSI), such as Lightweight Directory Access Protocol (LDAP) queries. However, every time that a user logs on to the domain from a Windows Vista-based client computer, the client computer takes a long time (about 10 minutes) to process the logon script. During this time, no other ADSI queries can be executed.

This issue occurs if the ADSI call in the logon script involves downloading a schema cache file.

On a Windows Vista-based computer that has a 1280 by 800 screen resolution, you reset the screen font size to the Larger scale (120 DPI) setting. However, when you restart the computer, you see that the logon screen is now clipped. Therefore, you have to scroll down the logon screen to enter your password.

Note: This issue does not occur when you use the Default scale (96 DPI) setting.

To develop a custom credential provider for Windows Vista, you use the ReportResult method to customize the string and the error icon that are displayed in a logon failure situation. However, when a logon failure occurs, the general error icon (CPSI_ERROR) is displayed instead of the customized error icon in the credential provider.

When you use an account from an external Massachusetts Institute of Technology (MIT) Kerberos realm to log on to a Windows Vista-based workstation, the logon fails.

Note: You can use the same account to log on to a Windows XP-based workstation.

Consider the following scenario:

• You work with a Windows Vista-based computer that is a member of a workgroup.
• On this computer, you try to access an administrative share that is located on another Windows Vista-based computer.
• The computer that you try to access is a member of a workgroup or a member of a domain. For example, you try to access the C$ administrative share.
• When you are prompted for your user credentials, you provide the user credentials of an administrative user account on the destination computer.

In this scenario, you receive the following error message:
Logon unsuccessful:

Windows is unable to log you on.
Make sure that your user name and password are correct.

If you try to map a network drive to the administrative share by using the Net Use command, you receive the following error message after you enter the correct credentials:

System error 5
has occurred. Access is denied.

Consider the following scenarios:

• An additional monitor is connected to a Windows Vista-based desktop computer. The additional monitor is designated as the primary display (the main monitor). The computer goes into hibernation or goes to sleep. This additional monitor is disconnected. The computer resumes from sleep or from hibernation.
• An external monitor is connected to a portable Windows Vista-based computer. The additional monitor is designated as the primary display (the main monitor). The built-in screen is designated as the secondary display. The computer goes into hibernation or goes to sleep. This external monitor is disconnected. The computer resumes from sleep or from hibernation.

In these scenarios, you cannot see the logon screen. Therefore, you cannot log on to the computer.
